For the collaborative dinners tonight and tomorrow, Crenn and Langhorne will alternate ten courses ($160); reservations are still available. So this week, there will be a little more Southern flavor on Fillmore Street, and ladies and gentlemen, Langhorne has already found some nasturtium.

Next up in Crenn’s guest chef series is Justin Cogley of Aubergine (July 17) and Scott Anderson of Elements (August 14-15).
